They grow actively during summer, the warmer it gets, the happier it is. so it can take good watering. I use cactus soil but I really make it very gritty adding in more pumice or top dressing it with chicken grit, so the base of the plant will not be too soggy. During winter time, I bring them indoors keeping them dry. Our winters have more rain, so as with most succulents, got to keep it dry during that period.
Summer conditions and sun intensity varies from place to place. We got strong sun here, so it does help it endure our triple digit heat with some shade from our city trees.
